AROHIBALD E. MONITT, OF HARTFORD, MICHIGAN,

WINDMILL.

SEECIPICATION forming part of Letters Patent No. 377,491, dated February 7, 1888.

Application filed June 24, 1887.

To aZZ whom it may concern:

Be it known that I, AROHIBALD E. MoNIr'r, a citizen of the United States, residing at Hartford, in the county of Van Buren and State of Michigan, have invented a new and useful Improvement in Windmills, of which the following is a specification.

My invention relates to an improvement in windmills; and it consists in the construction and arrangement of the parts of the same, which will be more fully set forth hereinafter, and pointed out in the claims.

The object of my invention is to provide a novel form of windmill, the wheel of which 1 is of a re-enforced construction, the central standard or shaft and the tail-vane support being constructed of gas-pipe, the parts being readily adapted to be thrown out of the line of the current of air and the operation thereof caused to stop, for the purpose of preventing injury to the mechanism of the mill when the wind is blowing at a high rate of speed. I attain this object by the construction illustrated in the accompanying drawings, wherein like 2 5 letters of reference indicate similar parts in the several views, and in which Figure l'is'a perspective view of my improved windmill. Fig. 2 is a rear elevation of the wheel and a portion of the standard,

0 showing the tail-vane thrown out of steering connection. Fig. 3 is a detail perspective view of the mechanism forthrowing the tailvane oug of relatively-operated position with the wheel. Fig. 4. is a detail view-of a portion of the wheel W.

A indicates the vertical standard, which is constructed of suitable gas-pipe or tubular material, and is mounted at its lower end upon a tubular casting, a,.secured to the turn-table 0 A. This turn-table A is secured to a suitable frame-work, A on the top portion of which a platform, A, is secured, as shown in the drawings. Upon the upper part of the tubular standard A a swinging yoke, B, is secured, in

the central portion of which the supporting pipe or arm B of the tail-vane is secured.

The yoke B is provided with two arms, which are formed with apertures, which are placed over the central tubular standard, A.

The aperture b in the lower arm of the said yoke B is constructed elongated, for the purpose of permitting a tilting motion in an up- Serial No. 242,409. (No model.)

ward direction of the said tail-vane. The top portion of the central standard, A, is provided with a hook, a, at its upper portion, to which one end of a brace wire or rod, b, is secured,

the other end of said brace wire or rod being secured to the central portion of the tail-vanesupporting arm. The central standard, A, has an arm, B projecting outwardly therefrom, near the upper arm of the yoke B, and under said armof the yoke, to retain the same in a fixed position upon the central standard, said arm B extending outwardly therefrom at an angle and having of itself an angular apertured proj ection, or cable is secured to the central portion of the arm B, and thence passes through the aperture in the angular projection b and extends downward through the central tubular standard, A, to within reaching distance from the ground. This rope or cable l is arranged in such a manner that it will have considerable purchase in relation to the arm B, so that when it is drawn downwardly it will'have a tendency to swing at the same time raise the said tail-vane in an inclined position to the central standard, A.

The shaft of the wheel W is mounted in a journal-box, 0, formed integrally with a yokecasting, O, which is mounted upon the central standard, A, in close proximity to the yoke B. An eccentric, O, ismounted on the inner end of the wheel-shaft, to which a curvedpitman, P, is secured eccentrically, and extends downward and engages with a wrist-pin, 19, secured to the upper portion of the rod, situated within the tubular standard A, and which is adapted to operate the water-power, as will be readily understood. This wheel W is constructed with a series of inclined blades suitably secured to binding rings or circles W, constructed of wrought-iron, at its outer and inner portions. These binding or supporting rings or circles If, as shown in the drawings. A rope the tail-vane inward toward the wheel in a plane parallel therewith, and,

W are secured to metallic strips w, projecting outwardly at an angle from the edge of the inner portion of each of the blades, and

the said rings W are of themselves united by brace-rods constructed of gas-pipe, which are secured directly to the outer rings W, and by means of small posts 10 to the inner rings W. By this means the said brace-arms W are partially projected out from the said fan-blades, 4

and are secured at their lower ends in a faceplate, W secured on the outer end of the shaft of the wheel'eutire. By means of this construction the wheel is not only re-enforced and strengthened, but is at the same time placed in themost advantageous position to engage with the current of air, as will be readily understood. The brace-rings W surround the entire inner portion of the wheels W, and the brace arms or tubes WV are arranged at regular predetermined intervals in connection therewith and as may be desired.

The novelty and utility of my improved device being obviously apparent and appreciable, it is unnecessary to further enlarge upon the same herein.

It is obvious that many minor changes in the construction and arrangement of the parts maybe made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, I claim- 1. In a windmill, the combination of the central standard, A, the yoke B, mounted thereon, having an elongated slot formed in the lower part thereof, and the support B of 1 the tail-vane, substantially as described.

2. The combination, with the blades of the wheel, of theinner and outer rings, W, the independent projecting angularly-arranged metallic strips secured at their ends, respectively, to the faces of the individual blades and the said rings W, the brace arms or rods W, 3 5 having their outer ends secured to the outer ring W and their inner ends secured to the hub of the wheel, and the posts 10, connecting the inner ring W to an intermediate point of the said rods W", substantially as described.

3. The combination, with the standard A, of the U-shaped yoke 0, connected at its ends to the standard, and formed at its center with a bearing, 0, the wheel having its shaft journaled in said bearing, the U-shaped tilting yoke B, having its ends connected to the standard A, the lower end being loosely attached thereto, and the vane bar or arm supported by the yoke B, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
